It’s like bringing a cartload of test equipment from the shop to the control room or the field. The TechChek 830-KP sources and reads DC like a milliamp or voltage calibrator, simulates and measures T/Cs & RTDs like a temperature calibrator, generates and counts frequency and Counts-Per- Minute like a frequency calibrator and displays pressure like a precision test gauge. Troubleshooting? It checks continuity with a beeper and measures AC line voltage like a multimeter! Calibrate Milliamp Inputs
